On a try

[JKinGA29]

My point is that the case book only refers to a case where the team has already made a request, hence the sentence "...once spotted the ball
may not be moved because of a second request." The point of the case is that once the team picks a place, they're stuck with that place unless there is a dead-ball foul or replay of the down. I don't see any case book plays where the team's first request regarding the ball is denied just because the ball has already been placed placed/spotted.

If the RFP hasn't been blown and the team hasn't yet made a request, I have no reason not to honor their request and move the ball. However once they pick a spot, or the RFP is blown, they're playing the ball where it lies unless there is a dead-ball foul or replay of the down.
